Definitions

  • the bore is aligned with the axis of rotation (1.3) of the tool (2) crossing across; in one of the side surfaces (4.1) of the driving hole, it cuts with a section of its circular cross-section a pivoting window, and at least one of the side surfaces (2.7) of the inserted into the driving hole polygonal driving pin (2.6) has opposite the Einschwenk hope an equally located and identically aligned MitEnglishemut ( 2.8), in cross-section preferably in the form of a circular cap, such that the eccentric shaft is in its neutral position with its flattening outside and in its clamping position within the driving hole and the axial movement of the driving pin (2.6) locks positively.
  • the adapter is an independent component that should be available in larger quantities. Each tool intended for use or in use should be permanently connected / screwed to such an adapter.
  • the adapter then allows by its particular configuration, which will be described below, a simple and quick tool change and a tight fit of the tool in the chuck with all the advantages in the context of the invention.
  • the axial position of the eccentric shaft is determined on the one hand by the locking screw 5.5.
  • a pivot lever is attached and shown at 5.6 in the neutral position, at 5.7 in the clamping position.
  • the pivot lever is located in a recess 5.1 within the enveloping cylinder of the chuck shell.
  • Fig.2 shows, the left standing part-section 5.3 of the eccentric shaft in the neutral position 5.6 of the pivot lever outside of the driving hole 4 and its side face 4.1 or introduced therein Einschwenk merits and the cam groove 2.8 of the opposite side surface 2.7 of the driving pin 2.6.
  • Tools such as e.g. Drills, stone drills, hole saws generate a lot of dust when used on construction in stone, mortar, wood, plastic, etc. be applied. Measures have been taken that this dust and dirt load does not hit and jam the clamping mechanism of the chuck.
  • the elasticity of the intermediate layer exerts a force on the end faces, which causes the end faces of the intermediate plate 2.5 and the face 1.2 are flat to each other and not rotate relative to each other during rotation due to misalignment of the shafts and the tool or lateral loads tumble and are then effectively sealed against dirt and dust.
  • the driving pin 2.6 thus has at least on one of its side surfaces 2.7 a cam groove 2.8, which has a circular cap-shaped cross-section with respect to the plane of the side surface, which essentially corresponds to the missing cross-section of the flattening 5.4 of the eccentric shaft 5.3.
  • a corresponding cam groove 2.8 is preferably provided in a square base area in each of the side surfaces of the driving pin. It therefore does not matter in which rotational position of the driving pin is inserted into the driving hole: It is in any case a cam groove 2.8 in front of the eccentric shaft, which is mounted in the peripheral wall of the driving hole in the driving hole secantial bore 5.2.
  • the pivot lever With the thumb of the hand holding the machine tool with the clamped tool, the pivot lever can be placed back in the neutral position 5.6 and pulled with the other hand of the driving pin 2.6 from the driving hole 4 and the tool from the chuck 1 are taken.
